My fear comes from the fact that I started taking a contraceptive pill 5 days ago which I know increases the chance of a blood clot. Basically my right leg started and continues to ache (about 12 hours now) and feel heavy and I've had random bursts of pain by my knee and down my calf and even my thigh. But I've also had the urge to keep moving it so I don't know if it could just be restless leg syndrome and I'm worrying for nothing but should I see my GP? There's no noticable swelling or redness apart from what looks and feels like a small bruise.
